Chinese covered bridges. [Kintaikyo Bridge] Iwakuni city Homepage > Dimensions. [Kintaikyo Bridge] Iwakuni city Homepage > Value. Structural Characteristics Each arch of the bridge consists of smoothly curved skeleton lines, its end support points restrained so that when a vertical load is applied to the curved surface of an arch, a horizontal reaction force is generated in the support points.

When subjected to free vibration, each arch prominently shows the symmetric mode of deformation inherent to an arch structure, as well as the asymmetric mode of deformation. In view of these characteristics, each of the central three spans of the Kintaikyo Bridge is considered to have an arch structure, and is the prototype of an arch bridge made of large-section, glue-laminated timbers. Each arch, resiliently retained at the end support points, provides different rigidities against small rotation and large rotation. Materials Timber As mentioned in Section 2-1-2, the kinds of timbers used for this bridge, locations of their use, sizes, and other details are specified in the ancient drawing created in 1699.

Stone Iron Site work. Pont en vague 1. Les Ponts couverts au QUEBEC. Huge timber steps form bridge built by students in rural China. This stepped timber bridge was built by a team of architecture students from the University of Hong Kong to provide a meeting place for residents of a rural community in southern China (+ slideshow).

Wind and Rain Bridge links two banks of a river on the outskirts of Peitian, a village in China's Fujian province. Designed by course leader Donn Holohan to be constructed without the need for mechanical fasteners, the structure takes its cues from the region's traditional wooden buildings and is formed from interlocking beams. "Designed solely in wood joinery inspired by traditional Chinese techniques, the bridge is a reinterpretation of the traditional covered bridge, which functions as a public space and a pedestrian connector," said the team. A team of 70 students assembled the 265 wooden components used to make the bridge under the watch of a local carpenter. Two roof structures, one hipped and the other an inverted pitch, shelter the bridge from the elements.
